When I first started to check out the water pump I removed the fan shroud. While doing so I got frustrated trying to snake it out and broke the bottom off.
Once I replace the water pump (tomorrow) I would like to put this shroud back on. I have 2 questions about this.
1. Do I need a fan shroud for more than personal safety? My uncle was saying no fan shroud could cause the engine to over heat.
2.if I peice the shroud back together should I us little bolts or zip ties? I'm planning on drilling small holes in each peice for a place to attach the two.

I would say the shrouds are pretty important on all ZJ's, even if yours doesnt try to run hot, it just might without the shroud, especially in the hot summer months. If its a trial rig, I would think the shroud would be even more improtant since you will be seeing more slow speed driving where the fan will need all the help it can get to pull air through the radiator and not around it. Fix it, replace, rig it up but try to keep most or all of it on there.

I broke mine on one side doing the same thing. Two holes and a heavy zip tie holds it together good and helps when it needs to come out again too! Jus cut it and put another in when done. I will add that I have a real clean break so it might not work so well for you!

That's kinda what I wanted to hear. Guess ill zip tie the broken pieces back together as they are lower profile. It's a fairly clean brake.

On a side note the coolant that came out got contaminated wit dirt/ rust so I will be replacing it. I was wondering if straight water will help it stay cooler? This fall I would put some antifreeze in for the winter.
